CANONSBURG, November 2006 – Aquatech International Corporation recently received an order from AES for their 800 MW Coal Fired Power Plant in the Commonwealth of Puerto Rico. This AES power plant operates on treated sewage as feed water and thus faces a combination of make up water treatment and discharge challenges.

Prior to obtaining the order, Aquatech worked diligently with the project site to pilot test equipment to arrive at the most optimum solution to solve the challenges faced by the customer. This order includes an Ultrafiltration Unit as pretreatment for an existing Demineralization Reverse Osmosis unit and Brine Concentrator followed by a Forced Circulation Crystallizer for a Zero Liquid Discharge (ZLD) System to evaporate the Demineralization Reverse Osmosis reject plus cooling tower blowdown.

Aquatech’s Ultrafiltration system will use Hollow Fiber membranes configured in two trains of 300 gpm each. The Ultrafiltration system will treat cooling tower blow down that utilizes treated sewage water for makeup to improve the quality of the feed water to the demineralization reverse osmosis unit.

The Brine Concentrator and Crystallizer system will utilize seeded slurry technology and will be capable of continuous operation, 24 hours per day, producing distillate for reuse in the process. As specified, the system is configured as 1 x 100% Brine Concentrators and 1 x 100% Crystallizer, processing 100 gpm of wastewater stream. The Crystallizer unit, specially designed to handle organic laden waste stream, will be fully integrated with the Brine Concentrator to produce semi-solid sludge to be disposed off-site.
